Higher Order Singular Value Decomposition #15

Dear Uni10 Developer,

I am pretty new in using Uni10. Recently, I was trying to write a MPS, which requires svd a lot. However, UniTensor seems don't support svd but rather higher order svd. Could you please provide some examples on this function? Because HOSVD is a little bit confusing to me.

I was trying to write a right canonical MPS from a random MPS. Was that possible within the code you have now? Thanks very much.

Yours Sincerely Baicai

The SVD is implemented in Block and Matrix.
You need to use UniTensor.getBlock() to get the pointer and perform SVD.
